Abstract
In the context of global warming and rapid urbanization, the surface urban heat island (UHI) effect has become increasingly serious. Research on UHI effect mitigation can provide useful references for urban planners and decision-makers, and is of great significance for sustainable urban development. However, few studies have considered UHI mitigation from a network perspective, not to mention the multi-level network. Therefore, oriented to the practical needs of urban master planning, this study took Hefei city as a case study, combined the methods of morphological spatial pattern analysis (MSPA), landscape connectivity analysis and circuit theory, and proposed a new approach for UHI mitigation by creating the ecological cooling network at multi-level. The results showed that: (1) 19 heat source patches and 24 cold source patches were identified, which were mainly distributed in the main urban area and the suburbs, respectively. (2) The central urban area had higher resistance values to the diffusion process of hot and cold air flow than the surrounding areas. (3) 71 corridors and 46 barrier points between cold-heat sources were obtained at metropolitan level, while 41 corridors and 70 pinch points between heat-heat sources were obtained at main urban area level. (4) The UHI effect can be potentially alleviated by strengthening the connectivity of cold-heat sources and breaking the connectivity of heat-heat sources. The approach proposed in this research can provide new insights for the compilation of climate-resilient urban planning and the formulation of UHI mitigation strategies.

3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management);
4. Energy efficient, low/zero carbon, and green buildings/communities;
5. Climate change mitigation and adaptation in urban environments;
6. Green infrastructure and BMPs;
7. Environmental Footprint accounting and management;
8. Urban agriculture and forestry;
9. ICT, smart grid and intelligent infrastructure;
10. Urban design/planning, regulations, legislation, certification, economics, and policy;
11. Social aspects, impacts and resiliency of cities;
12. Behavior monitoring, analysis and change within urban communities;
13. Health monitoring and improvement;
14. Nexus issues related to sustainable cities and societies;
15. Smart city governance;
16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society;
17. Big data, machine learning, and artificial intelligence applications and case studies;
18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems.
19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management;
